openrtb.2.6-202303.macro.auction_imp_ts

What it means

OpenRTB 2.6-202303 introduced macro.${AUCTION_IMP_TS}, which openRTB 2.6-202303 added an impression-fulfillment timestamp substitution macro..

Why it matters

macro.${AUCTION_IMP_TS} is only defined from 2.6-202303 onward. Used against an earlier version it is not valid, and a consumer below 2.6-202303 treats it as an unknown field.

How to fix it

Target OpenRTB 2.6-202303 or later when you send macro.${AUCTION_IMP_TS}, and make sure the value matches the type and any enum the specification defines for it.

Paste your bid request into the tester and select OpenRTB 2.6-202303 to see whether this rule fires against your payload.
